<p>Many businesses want to run their email servers on Linux, but getting started can be complicated. The attractiveness of a free-to-use and robust email service running on Linux can be undermined by the apparent technical challenges involved.&nbsp; Some of the complexity arises from the fact that an email server consists of several components that must be installed and configured separately, then integrated together. Unlike other approaches that deal with one component at a time, this book gives you a basic knowledge across all the server components, leaving you with a complete working email server for your small business network.<br /> <br /> Based entirely on free, Open Source software, you will see how to protect your server from spam and viruses, offer web access for remote access, and secure your installation with regular backups.</p>
